Description

Technical Field

[0001] The invention relates to the field of maternal and infant products, and more specifically to a milk shaker. Background Art

[0002] In the related art, some waterless milk shakers use hot air for heating, and the hot air heats the milk bottle to heat the milk bottle, so as to adjust the temperature of the refrigerated breast milk or brewed milk powder in the milk bottle, thereby achieving the purpose of warming the milk. In addition, the milk shaker basket in the milk warmer is reciprocated or circumferentially moved by a rack or belt structure to make the milk powder in the milk bottle evenly mixed, thereby avoiding the problems of milk powder agglomeration and granulation.

[0003] Most of the existing milk shakers use contact NTC temperature sensors to detect the temperature of the milk bottle. The reciprocating rotation of the milk bottle causes friction between the contact NTC temperature sensor, resulting in incorrect detection results. In order to avoid mutual friction between the contact NTC temperature sensor and the milk bottle, some milk shakers use an opening to set an infrared non-contact temperature sensor, which avoids friction after collision and completes the temperature measurement. However, the through hole for infrared rays to pass through will cause the sealing of the temperature measurement area in the milk shaking basket to fail, causing the internal structure to lose its sealing structure, and the infrared non-contact temperature sensor is easily affected by external airflow and liquid interference, resulting in a decrease in temperature measurement accuracy. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a milk shaker which can keep the temperature measuring area relatively sealed and has high temperature measuring accuracy.

[0006] As an improvement of the present invention, the heat-conducting cover is slidably connected in the through hole.

[0007] As an improvement of the present invention, an elastic member is provided between the heat-conducting cover and the heating cup.

[0008] As an improvement of the present invention, a fixing seat is fixedly connected or detachably provided in the through hole, the heat conductive cover is slidably connected in the fixing seat, and an elastic member is provided between the heat conductive cover and the fixing seat.

[0009] As an improvement of the present invention, the heat-conducting cover is provided with a first folded edge whose one side is axially limited by the fixing seat, and the other side of the first folded edge is in contact with the elastic member.

[0010] As an improvement of the present invention, the first folded edge is extended to have a second folded edge radially limited to the elastic member.

[0011] As an improvement of the present invention, a gap is provided between the second folded edge and the inner wall of the fixing seat.

[0012] As an improvement of the present invention, a wind shielding ring is provided on the upper portion of the fixing seat.

[0013] As an improvement of the present invention, the fixing seat is integrally formed of rubber or silicone.

[0014] As an improvement of the present invention, a sensor base is fixedly connected inside the base, and the infrared sensor is arranged on the sensor base.

[0015] After adopting the above structure, the milk shaker of the present invention has the following advantages compared with the prior art: the through hole can be shielded by setting the heat-conductive cover, and the heat-conductive cover can directly contact and conduct heat with the bottle in the heating cup, the heat-conductive cover can always fit with the rotation of the bottle, and can be directly positively correlated with the temperature of the bottle, there is no friction generated by relative rotation, so that direct heat transfer can be performed, and the relatively arranged infrared sensor can directly obtain the temperature of the heat-conductive cover to achieve accurate measurement.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] See attached Figure 1 -Attached Figure 3A milk shaker includes a base 100 and a heating cup 200 rotatably connected to the base 100, wherein an infrared sensor 110 is fixedly connected to the base 100, wherein a sensor base 120100 can be fixedly connected to the base 100, wherein the infrared sensor 110 is arranged on the sensor base 120100, and the structure is stable, wherein a through hole 210 is arranged at the bottom of the heating cup 200, wherein a heat-conducting cover 300 is matched in the through hole 210, wherein the heat-conducting cover 300 is arranged opposite to the infrared sensor 110, and the through hole 210 can be made 210 is shielded, and the heat-conductive cover 300 can directly contact and conduct heat with the bottle in the heating cup 200. The heat-conductive cover 300 can always fit with the rotation of the bottle and can be directly positively correlated with the temperature of the bottle. There is no friction caused by relative rotation, so that direct heat transfer can be performed. The infrared sensor 110 arranged relatively can directly obtain the temperature of the heat-conductive cover 300 to achieve accurate measurement. At this time, the heat-conductive cover 300 shields the through hole 210, and the temperature measurement area is relatively sealed, which avoids airflow and liquid interfering with the infrared sensor 110, so that the infrared sensor 110 can accurately measure the temperature.

[0022] See attached Figure 3 The heat-conducting cover 300 is flat-bottomed and converges downward along a certain arc to form a bowl shape. The flat bottom can better contact and conduct heat with various types of milk bottles, and the back of the flat bottom is easier to be arranged relative to the infrared sensor 110. The infrared sensor 110 can measure the temperature of the back of the flat bottom more accurately and quickly. The milk warmer can determine the model parameters of the milk bottle by obtaining the heating parameters of the milk bottle within a predetermined time period. The model parameters include the capacity, material, thickness and other specification parameters of the milk bottle, and query the pre-stored corresponding relationship table according to the model parameters of the milk bottle to determine the working parameters of the hot air component. In this way, a heating program can be selected for milk bottles with different specifications such as capacity, material, thickness, etc. The corresponding heat-conductive cover 300300 can be a single component or a composite component of a metal, graphene or other material with a high thermal conductivity. Ignoring a certain error, it can directly represent the temperature of the bottom of the milk bottle. By pre-setting the model parameters of the milk bottle, the working parameters of the hot air component can be directly determined according to the data measured by the infrared sensor 110, and the heat-conductive cover 300 makes the temperature measurement area relatively sealed, avoiding airflow and liquid interfering with the infrared sensor 110, so that the infrared sensor 110 can accurately measure the temperature. Compared with direct measurement, the model parameters of the milk bottle can be judged more accurately.

[0023] In order to further accurately determine the heating parameters, a corresponding relationship table of the temperature of the thermal cover 300 at different real-time temperatures at the bottom of the bottle can be established. It can be measured through experiments that the corresponding relationship table of the thermal cover 300 is copper-aluminum composite material and copper material has low thermal conductivity hysteresis, and the corresponding relationship table has a small deviation. The corresponding relationship table between the temperature of the bottle and the thermal cover 300 can be integrated into the model parameters of the bottle to directly determine the working parameters of the hot air component, making the heating efficient and fast. The thermal cover 300 structure can eliminate most of the interference and obtain the accurate temperature of the thermal cover 300. Correspondingly, the temperature of the bottom of the bottle can be accurately obtained, which can more accurately judge the model parameters of the bottle and make the heating efficient and fast.

[0024] Most baby bottles are made of glass, PP, PES, PPSU, silicone and other materials with low thermal conductivity. In addition, during the heating process, the surface temperature of the baby bottle is higher than the inner wall temperature of the baby bottle, that is, during the actual heating process, the thermal cover 300 will heat up at a higher heating rate than the liquid in the baby bottle. During the actual heating process, the air outlet temperature of the hot air component is the highest, followed by the temperature in the cavity, and then the surface temperature of the baby bottle. The surface temperature of the baby bottle is measured by measuring the thermal cover 300 and the infrared sensor 110. In the heating logic for measuring the liquid temperature, the heating curve of the thermal cover 300 and the liquid temperature can also be directly established. Since the thermal cover 300 has a large heating amplitude and a high rate, the error can be reduced to a large extent, so that the heating curve of the thermal cover 300 and the liquid temperature is accurate, and the heating can be efficient and fast.

[0025] The heat conductive cover 300 is slidably connected in the through hole 210, so that there is a large non-contact space between the heat conductive cover 300 and the infrared sensor, so that the closed measurement area is dynamically sealed, and airflow and liquid are prevented from interfering with the infrared sensor 110, so that the infrared sensor 110 can accurately measure the temperature. An elastic member 400 is provided between the heat conductive cover 300 and the heating cup 200, and the elastic member 400 makes the heat conductive cover 300 fully contact with the milk bottle to maintain accurate temperature measurement.

[0026] See attached Figure 3The through hole 210 is fixedly connected with a fixing seat 500, the heat-conducting cover 300 is slidably connected in the fixing seat 500, an elastic member 400 is arranged between the heat-conducting cover 300 and the fixing seat 500, the fixing seat 500 is an integral body, which can realize overall sealing, and ensure that the temperature measurement area formed by the fixing seat 500 and the heat-conducting cover 300 is not interfered by the outside world, the fixing seat 500 can be made of heat-insulating material, and can be integrally formed by rubber or silicone, and heat-insulating material can be further arranged between the fixing seat 500 and the heating cup 200 to further improve the measurement accuracy, or, the through hole 210 is detachably connected with the fixing seat 500, that is, the fixing seat 500 and the heat-conducting cover 300 are detachable as a whole, which is not only convenient for installation, but also convenient for maintenance and repair. The upper part of the fixing seat 500 is provided with a wind shield ring, which conflicts with the milk bottle, further avoiding the contact between the heat-conducting cover 300 and the hot air, and can more accurately and directly obtain the temperature of the milk bottle.

[0027] See attached Figure 3 The heat-conductive cover 300 is provided with a first folded edge 310 which is axially limited with the fixing seat 500 on one side, and the first folded edge 310 is in contact with the elastic member 400 on the other side, and has a larger force-bearing surface which is in contact with the elastic member 400, so that the temperature of the overall structure is reliable and the other side is axially limited with the fixing seat 500, and can remain stable after being in contact with the bottle for a long time and many times. The first folded edge 310 is extended with a second folded edge 320 which is radially limited with the elastic member 400, and the elastic member 400 can be sleeved to make the force more stable. A gap is provided between the second folded edge 320 and the inner wall of the fixing seat 500 to reduce friction interference and make the operation more stable.
